Lithium batteries for residential solar self-consumption

Lithium batteries for self-consumption allow energy generated by solar panels to be stored and used when photovoltaic production is insufficient or during the night. Thanks to their high efficiency, long lifespan and excellent storage capacity, they have become the preferred solution for residential solar installations.

These batteries help maximize the use of energy produced by photovoltaic systems, reducing dependence on the electrical grid and increasing household energy savings.

Why install a lithium battery in your home?

A lithium battery allows excess solar energy generated during the day to be stored and used later, significantly increasing the percentage of self-consumed energy.

• Greater energy independence
• Lower electricity bills
• Storage of excess solar production
• Backup power during outages
• Higher efficiency than traditional technologies

Typical applications

• Single-family homes
• Residential solar installations
• Grid-connected self-consumption systems
• Off-grid installations
• Holiday homes
• Country houses
• Backup energy systems
• Photovoltaic surplus storage
